SR 25 Columbia River bridge repairs start June 17

NORTHPORT - Improvements to the State Route 25 Columbia River bridge begin Saturday, June 17, and travelers and truckers should prepare for upcoming evening and overnight closures.

During an inspection earlier this year, Washington State Department of Transportation engineers discovered corrosion in some of the bridge’s components. Although the bridge remains safe for travel, WSDOT added counterweights and implemented restrictions across it in early 2017.

This project will require periodic evening and overnight closures between 7 p.m. and 5 a.m. beginning Tuesday, June 20. When the bridge is open, a temporary signal will continue to control one-way, alternating traffic across the bridge. The existing weight and width restrictions will remain in place.

Contractor crews from Northbank Civil and Marine will repair the bridge anchors and expansion joints underneath the bridge. This work should take about 30 days to complete. The contractor will work seven days a week until the job is done.

The 1,500-foot-long, steel-truss bridge was built in 1948. Located about 5 miles from the Canadian border, about 500-800 vehicles use the bridge every day.
